mien have. a toilet roll with hay in. a plastic guinea pig that wobbles that you put hay/parsley or basil in. a chubby tube. a huge pipe like a drainpipe to go in and out. just bought them a new wigwam as i washed the whole lot and it went abit funny. a plastic ball. but they mainly play with whatever has the hay or food in. or just hay and barley straw they like hiding under.
Mine love their fiddlestix. Also each set of piggies has a log cabin. The 3Bs like to sit on top of it but Bertie and Beryl go inside it - don't think they've ever even thought of sitting on it! They all love cuddle cups and I also have a piggie armchair from Pets at Home that they love to play on during floortime. I used to put it in the 3Bs hutch but the constant washing was ruining it
The 3Bs like playing with loo rolls but the 2Bs aren't bothered. However, the 2Bs like nibbling on a willow ball.
